Phase 1: Dramatic increase of acoustic emission due to the macromolecular connections. Phase 2: The acoustic activity is low, the deformation varies linearly with time. It’s the most dominant phase throughout the creep test. Phase 3: is characterized by a sudden acceleration of the AE rate causing the rupture of the material. Test 10 1 2 3 time Acoustic Emission distribution versus time M. Darwiche " estimation of the remaining lifetime on composite materials by modeling the acoustic emission appearance rate "

Conclusion An interesting step for lifetime prediction… if we have a specimen on use, ones we can localize t ref and then estimate the remaining lifetime. 26 Perspective: looking for relation into the second phase to estimate the remaining lifetime M. Darwiche " estimation of the remaining lifetime on composite materials by modeling the acoustic emission appearance rate " with t ref10%, we can estimate the rupture time from 0.4% of the integral lifetime with an error about 6.36%
